87C51FA FB FC PRODUCT OPTIONS

Intel’s extended and automotive temperature range products are designed to meet the needs of those applications whose operating requirements exceed commercial standards

With the commercial standard temperature range operational characteristics are guaranteed over the temperature range of 0 C to 70 C ambient With the extended temperature range option operational characteristics are guaranteed over the temperature

AUTOMOTIVE 87C51FA FB FC-20
range of b40 C to a85 C ambient For the automotive temperature range option operational characteristics are guaranteed over the temperature range of b40 C to a125 C ambient The automotive extended and commercial temperature versions of the MCS-51 product families are available with or without burn-in options

As shown in Figure 2 temperature burn-in and package options are identified by a one- or two-letter prefix to the part number

PIN DESCRIPTIONS

VCC Supply voltage

VSS Circuit ground

VSS1 Secondary ground in PLCC only Provided to reduce ground bounce and improve power supply by-passing

NOTE This pin is NOT a substitute for VSS pin 22

Port 0 Port 0 is an 8-bit open drain bidirectional I O port As an output port each pin can sink several LS TTL inputs Port 0 pins that have 1’s written to them float and in that state can be used as high-impedance inputs
